2020-07-10 00:25

Beijing Yuji is one of the manufacturers of fluorine-containing chemicals, which has the production and purification technology of cis-1-Chloro-3,3,3-trifluoropropene (HCFO-1233zd-Z), whose purity can arrive Grade 2N5(99.5%).

1-Chloro-3,3,3-trifluoropropene has the ozone depletion potential of 0 (approximately) and very low global warming potential (GWP). It exists as two different stereoisomers, cis-1-Chloro-3,3,3-trifluoropropene (HCFO-1233zd-Z) & trans-1-Chloro-3,3,3-trifluoropropene (HCFO-1233zd-E), which have different boiling points and possibly perform differently in different applications. HCFO-1233zd-Z has the GWP of 1, boiling point of 39℃ and melting point of -101℃. It has a favorable toxicity and shown good compatibility with many plastics and elastomers commonly encountered in equipment presently. HCFO-1233zd-Z is a novel, non-flammable, odorless liquid that could be used as a kind of environmentally-friendly cleaning agent.

As a kind of cleaning agent, it is now commonly used in mechanical parts degreasing. In the year of 2018, Central Glass Co., Ltd formally published the commercial product “CELEFIN 1233Z”, which has shown an outstanding property and rapid efficiency in degreasing, including cutting oil, spindle oil and hydraulic oil etc. The data illustrates that it has been more and more popular in Japanese cleaning market in these two years, better than those traditional cleaning agents. Meanwhile, it also benefit from the implementation of stringent environmental policy and regulations.

On June 17, 2020, The Threebond Co., Ltd. just applied a new international application. The present invention relates to a cleaning agent and relates to a cleaning agent which is suitable for cleaning machine parts, electrical and electronic equipment parts, optical equipment parts, and building materials, and particularly suitable for cleaning contamination caused by grease or the like on a surface of metal or resin of transportation equipment such as an automobile, train car, or the like.

The invention provides a cleaner composition, a cleaning aerosol, and a method for cleaning a contaminated part, in which the contaminated part, particularly a part around an automobile brake or the like, can be cleaned easily, safely, and with high efficiency and minimal environmental impact. The present invention is a cleaner composition including: a component (A); cis-1-Chloro-3,3,3-trifluoropropene (HCFO-1233zd-Z) as a cleaning agent; and a component (B); carbon dioxide (CO2) as a propellant; wherein a content of the component (B) contains 1.6 to 10 parts by mass with respect to 100 parts by mass of the component (A).
